One of the show's veterans has decided to part ways with the NBC reality show, and we're not sure what exactly happened!

Here was what NBC said in a statement:

"After helping hundreds of contestants transform their lives and inspiring millions of viewers at home, The Biggest Loser and Jillian Michaels have decided to part ways and she will not be returning for season 16 when it airs in the fall."

This isn't the first time that Jillian has left the show, however. After debuting with the show in 2004, she bounced in 2006. She came back in 2007, but then left again in 2011 and stayed away for the 12th and 13th season before returning for the next two seasons.

Does that mean there's a chance that Jillian will appear on the show again the future? Maybe the reality personality is just taking a bit of a hiatus?

We would normally assume that was the case if it wasn't for all of the drama that happened in February after the contestant Rachel Frederickson won after a HUGE weight loss that saw her drop from 260 to 105 pounds, and had many fans upset that the show seemed to favor possibly unhealthy and drastic weight loss rather than going the slower, probably more boring yet WAY more healthier route.

After that shocking finale, Michaels said:

"We are allowed to speak with our contestants after they go home…but no one had told me, 'Hey, Rachel is very, very thin.' Bob [Harper] and I had no idea. Nobody had told us, nobody had said anything to us, so yes, I was stunned. Obviously, I thought she had lost too much weight and I was immediately concerned and wondering how this happened, how no one had said something to me and how the checks and balances that have been put into place, in my opinion, this had fallen through those checks and balances."

Sounds like she was definitely peeved off about that, and could have absolutely prompted her exit!

Jillian Michaels hasn't talked about her release yet, and the show hasn't announced a replacement for her either, so we guess we'll just have to wait and hear what happens.

"My metabolism actually changed like crazy this year. I have Hashimoto's disease. It's a thyroid disease, and it's now been two years since taking the medication for it, so for the VS show I didn't want to lose any more weight, I just want to have muscles in the right place, and if my butt can get a little perkier, then that's good."
